so, i'm having this problem with my t-line design. i want to put this one 8" jbl gt82d in a tline box for my room.
specs for the box:
port length: 6ft
port area: 30-33cu in
line is flattest around 44hz on winisd at 1cu ft
the box is tuned to 32hz and i'd like to get it to 44. making the box smaller or changing the port area(smaller) will raise the tuning. if i do that, though, the box gets too small(around .5-.8).
